Abstract

The invention discloses a transmission treatment method of an optical fiber repeater and a variable-channel transmission optical fiber repeater, wherein the repeater comprises the modules of a power supply, a microprocessor, an antenna feeder system, a plurality of radio receivers, a plurality of radio transmitters, optical fibers, a wavelength division multiplexer, a wavelength decomposition multiplexer, a radio signal division mixer, an optical transmission signal adaptor, an optical transmission interface and the like. The invention is capable of providing radio communication relay transmission service for all radio communication system users in special regions and tunnels, meets the requirements of reducing the number of antennas, reducing the number of the used optical fibers, reducing mutual interference among systems and meeting the insulation among the systems, is capable of realizing long-distance optical transmission relay among the optical fiber repeaters when the optical fibers are cascaded to the optical fiber repeaters, and has the characteristics of being applicable to a plurality of radio communication systems for relay transmission.

Description

technical field [0001] The invention is a wireless communication relay transmission technology, which is suitable for relay transmission of a wireless communication system in a weak field section, and belongs to the technical field of wireless communication. Background technique [0002] In the current wireless system, there are many kinds of wireless communication systems, such as GSM, CDAM, WCDMA, TD-SCDAM, CDMA2000 and other wireless communication systems. In the existing technology, there are dedicated optical fibers for the above wireless communication systems. The repeater is used as a relay device, but due to some special areas and tunnels, due to the limitations of the antenna installation space and the number of optical fibers brought about by its location and building boundaries, the network planning of each wireless communication system is inconsistent, and the network planning of each system is inconsistent. Influenced by factors such as base station location, op...
